ROLLER AND FLEXIBLE SHEET.

Specification of Letters rateut.

Application filed May 29, 191-5. Serial-NO. 31,129.

To all whom it may concern:

Be it-know'n that I, WARREN W. HELLE, a citizen of the United States, residing at Hinsdale, in the county of Dupage and State of Illinois, have invented new and useful Improvements in Rollers and Flexible Sheets, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying draw ing, forming a part of this specification.

My invention relates to a flexible sheet and'rol-ler support therefor, and more specifically to such a device used as a telephone directory and provided with means whereby it may be secured to the mouth-piece of the telephone.

One of the objects of my invention is to provide a device of this character which shall be simple in construction, neat in appearan e and eflici'ent in use.

Further objects will appear from the detaileddes'cription to follow taken in connection with the appended claims.

7 In the accompanying drawings in which I have shown one embodiment of my invention Figure 1 is a front elevation showing the directory in position on the telephone.

Fig. 2 is a side elevation of the parts shown in Fig. 1;

Fig. 3 is a vertical axial section through the-roller showing" the manner in which the roller is held in place in the bearing caps, and the bearing caps in theframe, and showing the manner in' which the rewinding' s ring is secured to the bearing cap and to the roller;

Fig. 4 is a section on the of Fig. 3 showing the manner in which the flexible strip is secured to the'roller,

Fig. 5isa perspective view of the bar by which the spring is connected to the roller Fig; 6 is a erspective view of the roller.

Referring now" to the drawing in detail I have shown my improved device in cons st: tion with a telepho'necornprising a standard 10,- a transmitter easing 11 and a mouthpiece 12. The device aseir comprises a rollersupportingmember 13, a roller 14, and a flexible sheet 15 secured to the roller. The-supporting member comprises" a ring portion 16 which loosely surrounds the mouthpiece 12""o'f the telephone, downwardly extending pea-1611s 17 whichar'eheld in proper position relative to each other by means of a strip 17 bent therearound, outwardly extending portions 18, forwardly extending portions 18 and ring portions 19 in which the bearing caps 20 and 21 for the roller are secured. These bearing caps 20 and 21 fit somewhat tightly in the ring por tions 19 so that they are held securely and prevented from rotation. The ring portions 19 may be somewhat springy and yield slightly when the caps are fitted in place. The cap 20 comprises a dished portion 22 to receive theend of the roller, and flange portion 23 which engages the ring portion 19 to position the cap with respect then'eto.

The cap 21 comprises a dished portion 24 to receive the other end of the roller 14 and flange portion 25 to engage one of the ring portions 19. The roller 14 is slotted or split longitudinally, as shown at 26, to permit the flexible sheet 15 to be easily secured thereto, this flexible sheet having a small rod 27 secured thereto at its upper end; the rod 27 with a portion of the flexible sheet 15 lying within the roller 14', as shown in Fig. 4, and the flexible sheet extending out through the slot 26.

In assembling the roller and flexible sheet the edge of the sheet is slipped into the slot 26 at one end of'the roller, theend of the rod 27 lying within the roller and the sheet and rod are" then slipped over sidewise until the rod 27 is entirely withinthe roller 14. The rod 27 is large enough so' that it will not slip out through the slot 26.

A red 28 is secured to the lower edge of the sheet 15 and is provided with a ring portion 29 by means of which the sheet may be unwound from the roller. The means for rewinding the sheet 15 on the roller after it has been unwound therefrom comprise a bar 30 secured to the roller and a spring 31 secured to the bar and surrounding it and having one end 32 secured beneath struckup portions 33 of the cap21. The bar 30 is provided with wing portions 34 about which the end of the spring 31 is wrapped to secure the spring and bar together, and is also providedjwith lugs 35 which fit within recesses' 36 in therolleri to prevent relative r0- tation between the bar 30 and the roller. The outer edges 0f the wings 34 engage snugly within the roller 14 to in positienin the bar with respect t0 the roller.

Patented July 9, 1918.

The flexible sheet 15 maybe ruled to provide a column 38 for the names which are to be placed on the directory, a column 39 for theexchange, and a column 40 for the and the ring portion 16 is slipped over the mouth-piece which is then screwed back in place. When it isdesired to look up a num her on the directory the sheet 15 is unwound from the roller by pulling downwardly on the ring 29. It will be noted that because of the fact that the ring portion 16 fits somewhat loosely on the mouth-piece 12 that a sidewise pull on the sheet 15 when it is being unwound will not cause the edges of the sheet to berubbed and worn against the flanges 23 and 25, as the supporting member I 13 will swivel about the mouthpiece 12 so that the sheet 15 will unwind properly. a

In assembling theroller 14, bar 30, spring 31 and cap 21, the bar 30, spring 31 and cap 21 may first be assembled, after which the bar over the end of the roller, and the caps 20 30 and spring 31 may be slipped within the roller 14, the slot 26 being wide enough so that when sprung a little the wing portions 34 can be slipped between the edges of the slot 26. The wings 34 are slipped along until they come out at the other end of the roller 14 when they may be rotated a quarter turn to permit the lugs 25 to seat in the recesses 36. The sheet 15 is then securedin place as described above. After these parts have been assembledthe cap 20 is slipped of the supporting member 13, the ring portions 19 being sprung outwardly slightly to permit the caps to be put in place.

When the sheet 15 is unwound from the roller the latter rotates within the bearing caps 20 and 21.

It will be noted that I have provided a device which is extremely simple in construction, and which may be made almost entirely from stamped sheet metal and bent wire parts.
